Plain English
The registry is where compact strings get meaning.
Technical summary
Registry records map identifiers to definitions, allowed profiles, localized labels, examples, negative cases, reversibility levels, and validator expectations.
Deep spec
Neither Unicode nor PUA assigns JustAnIota semantics. PUA is private-use only, and public meaning must be carried by the registry plus validation evidence.
Registry entry requirements
- Stable ID and human-readable label.
- Plain-English definition.
- Allowed profiles and payload positions.
- Locale notes and direction-sensitive warnings.
- Positive examples, negative examples, and validator issue behavior.

This local registry is a demo snapshot. It shows the fields a real signed registry record needs: ID, definition, code point, mode, reversibility, examples, and policy notes.
Unicode and PUA do not assign these meanings. The registry does, and a production registry must be versioned, signed, immutable after assignment, and validator-tested.
